4.7.1.3Cable Lock Provision

These systems include a chassis cutout (on the rear panel) for the attachment of a cable lock mechanism.

4.7.1.4I/O Interface Security

The serial, parallel, USB, and diskette interfaces may be disabled individually through the Setup utility to guard against unauthorized access to a system. In addition, the ability to write to or boot from a removable media drive (such as the diskette drive) may be enabled through the Setup utility. The disabling of the serial, parallel, and diskette interfaces are a function of the LPC47B367 I/O controller. The USB ports are controlled through the MCP.
